Buster Cannon

The Buster Cannon is one of Future Trunks' core offensive techniques. To perform it, he extends both arms straight forward, palms facing the target, and channels an enormous amount of energy before releasing it as a wide, destructive beam. Unlike the Burning Attack with its elaborate hand movements, the Buster Cannon is straightforward and efficient, built for raw power rather than tactical misdirection.

The technique is considered the base form from which the Burning Attack was derived. Where the Burning Attack adds a diamond formation and deceptive hand flourishes, the Buster Cannon strips away all pretense and delivers maximum energy output with minimal windup.

The Buster Cannon first appears in Dragon Ball Z: The History of Trunks, the special that depicts Future Trunks' desperate life in a timeline ravaged by Androids 17 and 18. In this bleak alternate future, Trunks uses the technique during his futile battles against the android menace, pouring everything he has into blasts that ultimately prove insufficient against the mechanical terrors that killed his mentor, Future Gohan.

The attack also features in Dragon Ball Z: Bio-Broly, where Trunks (the present timeline version) employs it against the titular clone monster. The technique's simplicity makes it a reliable fallback when more complex attacks are impractical.

Across video games, the Buster Cannon frequently appears alongside the Burning Attack in Future Trunks' moveset, often serving as his secondary special or super attack. Some games have even conflated the two techniques, listing one as an alternate name for the other due to their visual similarities.

The technique represents the pragmatic side of Future Trunks' fighting style. Where the Burning Attack is theatrical and designed to set up sword combos, the Buster Cannon is a pure damage dealer meant for situations where only overwhelming force will do.
